格形地下连续墙是悬臂式基坑支护结构的一种形式,由于其造价昂贵,一般仅用作大深度基坑的自立式围护结构。对部分采用格形地下连续墙围护的某船坞基坑格形地墙的实测水平变形进行了较为详细的分析,总结了格形地下连续墙围护结构水平变形的一些规律,指出了自立式格形地下连续墙变形计算存在的不足,提出了格形地下连续墙围护设计中仍需进一步研究的问题。
Lattice-shaped diaphragm wall is a form of cantilever foundation pit support structure, due to its high cost, generally only used as a large deep foundation pit free-standing enclosure structure. The measured horizontal deformation of the wall of some dock foundation pit which is enclosed by the lattice continuous diaphragm wall is analyzed in detail. Some laws of the horizontal deformation of the lattice continuous diaphragm wall are summed up. The deficiencies of the deformation calculation of the continuous diaphragm wall with lattice shape are analyzed. The problems that need to be further studied in the design of the continuous diaphragm wall with lattice shape are put forward.
